How Long Should a Car Warm Up?
1 Answers
Car warm-up only takes 1 minute. The harm of not warming up the car includes: causing engine wear as the engine oil settles at the bottom when the car is cold, leaving the engine internals in a state of dry friction. The method for warming up is: after starting the vehicle, let it idle for 1 to 2 minutes to allow the engine coolant to reach normal temperature before driving. The benefits of warming up are: 1. After prolonged parking, the engine oil flows back into the oil pan, leaving the upper part of the engine without proper lubrication; warming up helps lubricate it. 2. When the engine hasn't reached operating temperature, the fuel system cannot effectively vaporize gasoline completely due to low temperature; warming up improves efficiency. 3. It helps the transmission gear oil to lubricate the upper part of the transmission.
